Biostatistics Assignment-

Consider the data given in problem 6 of KKNM Chapter 5. Use SAS to perform the regression predicting ATST from AGE. For this, you can use something like the SAS code given below. The dataset is attached (ch05q06). The dataset is in SAS format so you can use LIBNAME statement to read the data directly. Depending on where you save this dataset, you will need to modify the file location on the LIBNAME statement below.

OPTIONS NOCENTER;

LIBNAME aa 'C:\Subhash\UIC BSTT 401 Spring 2019\Data\datasets\SAS\CH05';

PROC MEANS DATA = aa.CH05Q06;

RUN;

PROC REG data = aa.ch05q06;

MODEL Atst = Age;

RUN;

PROC PLOT data = aa.ch05q06;

PLOT Atst * Age;

RUN;

Based on your analysis, answer the following questions.

1. For the linear regression model, what are the fitted regression coefficients and their associated standard errors?

2. What is the regression variance, or more symbolically what is S²Y|X?

3. Use the computer to plot the observed data, and then use your hand and a pencil (or pen for those confident people out there) to draw the fitted regression line.

4. What is the value of the test statistic for testing whether the slope is 0? Please report two test statistics for this.

Instructions - This is the book we are using for the course Applied Regression Analysis and Other Multivariate Methods (4th/5th edition) Authors: Kleinbaum, Kupper, Nizam, & Muller. Please see attached for instructions on how to download the data sets using SAS. I was trying to open the data sets with SAS but I was having issues. However, I have the dataset attached with the homework instructions as well. In case you are having issues opening the required data sets to be use, is on chapter 5 problem 6 of the book. If you can't get it, just let me know I have the book so I can copy the datasets for you. Each problem is worth 3.125 pts. Submit edited output from SAS with the relevant information. Highlighting your answer in SAS output with messages like “See page … in the SAS output ” is not acceptable.
